Class BlankCondition

java.lang.Object

com.norconex.importer.handler.condition.impl.BlankCondition

All Implemented Interfaces:

Configurable<BlankConditionConfig>, Condition, ConfigurableCondition<BlankConditionConfig>, FailablePredicate<DocHandlerContext,IOException>

public class BlankCondition
extends Object
implements ConfigurableCondition<BlankConditionConfig>

A condition based on whether the document content (default) or any of the specified metadata fields are blank or inexistent. For metadata fields, control characters (char <= 32) are removed before evaluating whether their values are empty. Dealing with the document content will instead check if it is null or empty (no bytes returned when read).

Multiple fields and values:

By default, ALL values for all fields matched by your field matcher expression must be blank for this condition to be true. You can change the logic to have ANY values to be blank for the condition to be true with BlankConditionConfig.setMatchAnyBlank(boolean).

If no fields are matched, the conditions is also considered empty (true).
